. I) 4 v Application filed June 10, 1927. Serial No. 197,858.

The invention relates to an oil burning device, as described in the present specification and illustrated in the accompanying drawings that form part of the same.

' The invention consists, essentially of the novel features of'construction pointed outbroadly and specifically in the claims for novelty following a description containing an explanation in detail -ofv an acceptable 1 W'formof the invention.

} Theobjects of the invention are to elimihate the use of a readily destructible mate- .rial in th'e construction of heating'devices designed for the consumption of oil as fuel; 5 to economize in so far as maintenance charges are concerned vand in the fuel'consumed'; to insure an efiicient mixture andple and economical construction and of a durable nature. so; Inthe drawings, Figure-1 is a plan view of the burner. Figure 2 is a vertical sectional view. Y fFigure 3 is a horizontal sectional view on Y .the line in Figure 2. as" Like numerals of reference indicate correzsipnding parts-in the various figures; 1 ferring to the drawings,-the base, 10 is o formed of refractory materialand is circu lan inshape and eoptained within.-.tl1e metal '40 casmg 11 and resting on this .base within the wall of the casing 11, the refractory wall 12 encloses the combustion chamber v13 'and this wall 12; is formed with the annular recess 14 with the inclined 'walls' 15 and 16 '45 meeting in the curve 17 and. extending from 4 the upper vertical motion 18 and lower verj-tical'section 19.' Q I -1The refractory cone centre, piece 20' is formed with a base 21' having to outlet slots 22 leading intothe heat disu ep 23 i the centre of the cone,

'- rection of the flow.

a plurality of which tapers downwardly to the base 21 from the annular vertical surface 24 spaced from the upper vertical section, 18 of the wall 12. The upper surface 25 of the cone- 20 converges from the vertical surface 24 to the edge of the heat discharge passage 23 and to the surface 25 the braces '26 are at tached and extend to the casing 11- to which they are secured. 7

The fuel inlet 27 enters the combustion chamber'13 in the direction of the centrifugal flow of the heating gases and similarly the fuel inlet 28 diametrically opposite enters the combustion chamber 13in the di- The air pipe 29 extends "into the inlet 27 and the fuel mixture pi e 30 of. much and is connected to suitable feed mechanism fuel inlet 28 and a fuel mixture pipe 32 into "the pipe 31,"th'us providing a feed inthe direction of the "flow at two or more places. 7 In'the operation of the oil burning ,de-A

smaller diameter extends mto the pipe 29 a and likewise an air pipe31extends into the vice the fuel is fed in throughthe fuel mix- 4 I ture pipes and. the secondary air is drawn in through the surrounding air ipes and after ignition, not shown herein,'t e ignited heating gases flow around the. combustion chamber and during burning operations the surfaces 17 and 24. thereby thinning the. mixture. 'The combustible gases. flow at great speed centrifugally and are directed by the wall 16 and the tapered portion of the cone to the outlets 22 through which the heated air flows to-the discharge passage 23,- in fact the whole burner includmg the passage 23 is a mass of flame and'hotair, so

that in heatingsystenis the water is. kept at secondary air is drawn in between the wall I a high temperature at a minimum expense in regard-to fuel. I

What I claim 1. In an oil burning mechanism, a casing,

a centre piece of refractory material braced from the casing and tapering to outlet openings leading to.a central vertical discharge passage. forming a heat director.- a

base of refractory materialfor said centre piece and'anencircling wall spaced from said-centre piece and form ng therewith an annular combustion chamber having upper air openings thereinto and feed passages constituting primary mlxlng chambers.

2. In an 011 burning mechanism, a casing,

. a centre piece'tapering at its lower end to outlet openings leading to a central vertical passage forming a heat dlrector, a base for sa1d centre piece and an enclrchng Wall having an annular recess havingdnclined walls meeting in a curve and forming with said 1 centre piece an annular combustion chamber having upper air openings -thereinto and feed passages constituting primary mixing chambers.
